Coil calibration

We conduct coil calibrations to deliver accuracy, consistency and suitability when our thermocouples are used in temperature measurement applications.

What is a coil calibration?

Coil calibration is the method used to qualify a reel or coil of thermocouple wire / cable as suitable for use in temperature measurement applications.

All aerospace and automotive heat treatment specifications confirm coil calibration as an approved way of identifying and qualifying a coil or reel of thermocouple wire or cable.

Coil calibration is used for

Base (K, N, T or J) and Noble (R, S or B) metal thermocouple combinations.

Coil calibration a win-win method.

Test

Base metal thermocouples

Coil calibrations are conducted using the comparison calibration method on base metal thermocouple combinations, by sampling and calibrating both ends of a coil of base metal thermocouple wire or cable. This is conducted over a wide calibration temperature range, allowing both accuracy and consistency of the coil to be established. Thermocouples can be manufactured from the remaining coil length and data from the coil calibration can be attributed to the finished thermocouples. This provides a detailed wide temperature range of calibration data for the thermocouples which gives a significant saving from the conventional individual thermocouple calibration method.

Test

Noble metal thermocouples

Coil calibrations can be conducted using either the fixed point or comparison calibration method on noble metal thermocouple combinations. The advantages of coil calibration as indicated for base metal thermocouples apply when using the comparison calibration method with the opportunity of the highest level of accuracy, when the fixed point calibration method is used.

Coil calibration and the combination of high quality materials and manufacturing methods have been pioneered by CCPI Europe to enable customers to have the most cost effective, long life temperature sensors without compromising accuracy.
